## Background
BACKGROUND
1. Technical Field
The present disclosure relates to street lamp monitoring systems, and particularly to an LED (light emitting diode) street lamp and a remote intelligent monitoring system for monitoring and controlling the LED street lamp.
2. Description of Related Art
Street lamps are a public facility in cities. However, monitoring street lamps, such as checking functional defects in street lamps, has not been properly resolved. Although the monitoring can be easily automated, it proves to be difficult to identify the defects precisely, and to localize the malfunctioning lamps with the aim of programming repair. This difficulty is furthermore considerably increased with the number of the street lamps and the monitoring zones increase.
Therefore, there is a need to improve the monitoring systems to make them more efficient and environmentally friendly.

DETAILED DESCRIPTION
Referring to FIG. 1, a remote intelligent monitoring system 100 for monitoring and controlling LED street lamps is provided. The monitoring system 100 includes a server 2 and a number of LED street lamps 3.
In the embodiment, the LED street lamps 3 each communicate with the server 2 via wired technology, wireless technology, or the combination of wired technology and wireless technology. For example, the LED street lamps 3 transmit data to a relay terminal 6 via Power Line Communication (PLC), Optical Fiber Power Line Communication (OPLC), ZIGBEE, or WIFI technologies. And then the relay terminal 6 receives and transmits the data to the server 2 via Internet, 3G, 4G, GPRS, CDMA, or GSM mobile network technologies. For another example, the LED street lamps 3 transmit data directly to the server 2 via Internet, 3G, 4G, GPRS, CDMA, or GSM mobile network technologies.
In a first embodiment of the LED street lamp 3a, as shown in FIG. 2, each LED street lamp 3a includes a lamp board group 32, a processing unit 33, a sensing module 34 and a detecting module 36. The lamp board group 32 includes a number of lamp boards 321 connected in parallel. An LED light source 3211 and a power driver 3212 are distributed on each of the lamp boards 321. The LED light source 3211 includes a number of light emitting diodes connected in series. The power driver 3212 receives electrical power from an external source (not shown), and converts the power to a proper direct current (DC) supply, to drive the LED light source 3211 to emit light.
The sensing module 34 includes many types of environmental sensors (not shown) configured to detect atmospheric information of the area where the LED street lamp 3a is located. In this embodiment, the atmospheric information include, but are not limited to, radiation from the sun, humidity, air pressure, wind speed, or air quality.
The detecting module 36 is connected to each LED light source 3211. The detecting module 36 detects the electrical characteristics of each LED light source 3211. In this embodiment, the electrical characteristics include, but are not limited to, the amount of current flowing through each LED light source 3211 or the voltage applied to each LED light source 3211.
In this embodiment, the LED street lamp 3a further includes a storage unit 35 configured to store many kinds of atmospheric conditions and many specified electrical standards corresponding to each of the atmospheric conditions.
The processing unit 33 includes a control circuit 331 and an analysis module 332. The analysis module 332 is connected to the detecting module 36, the sensing module 34 and the storage unit 35, and receives the detected electrical characteristics from the detecting module 36 and the detected atmospheric information from the sensing module 34. The analysis module 332 reads the specified electrical standards corresponding to the detected atmospheric information from the storage unit 35, and determines whether the detected electrical characteristics are consistent with the specified electrical standards. If the detected electrical characteristics are not consistent with the specified electrical standards, the analysis module 332 is further configured to generate a control command including the specified electrical standards.
The control circuit 331 is connected to each one of the power drivers 3212 and the analysis module 332, and adjusts the electrical characteristics of the LED light sources 3211 to accord with the specified electrical standards via the power drivers 3212, in response to the control commands, so as to control the functioning of the LED light sources 3211, for example, switching on or switching off any one of the LED light sources 3211, or adjusting the luminance or a color temperature of the light emitted by any one of the LED light sources 3211.
In this way, the LED street lamp 3a is able to function directly and automatically in a stand-alone mode, without the intervention of the server 2.

Referring to FIG. 4, the server 2 includes a second communication module 21, a control module 22, a processing module 23 and a storage module 24. The second communication module 21 receives the detecting signal from each LED street lamp 3b. 
In this embodiment, the first communication module 37 communicates with the second communication module 21 via wired technology, wireless technology, or a combination of wired technology and wireless technology.
The processing module 23 is configured to parse the detecting signal to obtain the unique identification code and the detected electrical characteristics of the LED street lamp 3b, and the atmospheric information detected by the LED street lamp 3b. 
In this embodiment, the storage 24 stores a normal value interval of electrical standards under normal conditions. The processing module 23 is further configured to determine the functioning of the LED lamps 3b by determining whether the detected electrical characteristics in the detecting signals is in the normal values interval of the electrical standards. If the detected electrical characteristics are out of the normal interval of the electrical standards, the processing module 23 determines that the LED lamps 3 is in a malfunction condition, and further determines malfunction information and locations of the malfunctioning LED street lamps 3b. The control module 22 activates functions of the server 2 to give a warning and display the related malfunction information, in response to the malfunction information and location of the malfunctioning LED street lamp 3b. 
In this way, the LED street lamp 3b is able to report any abnormalities to the server 2, and the server 2 is able to localize the malfunctioning lamp, so that a potential defect can be discovered and repaired in a timely manner.
In this embodiment, the storage module 24 further stores many kinds of atmospheric conditions and many specified electrical standards corresponding to each of the atmospheric conditions. The processing module 23 is further configured to read the specified electrical standards corresponding to the detected atmospheric information from the storage module 24, and determine whether the detected electrical characteristics are consistent with the specified electrical standards. If the detected electrical characteristics are not consistent with the specified electrical standards, the processing module 23 is further configured to generate a control command including the specified electrical standards. The second communication module 21 receives and sends the control command to the corresponding LED street lamp 3b. 
In this way, the server 2 is able to monitor the functioning of each individual LED street lamp 3b, and switch on or switch off the LED street lamp 3b, or adjust luminance or color temperature of the light emitted by the LED street lamp 3b. 
In a third embodiment of the LED street lamp 3c, as shown in FIG. 5, a difference of this embodiment from the first embodiment is that the LED street lamp 3c includes a lamp board group 32′ and a power driver 31.
